In just a couple months, Samsung’s Galaxy S 5 should be going official, and we’ll be able to finally know which rumors were leading us down the true path to the phone’s launch hardware, and which led us astray. For the moment, though, it’s anyone’s guess who’s on-target and who’s missing the mark, leading to an atmosphere chock full of contention. Just a few hours ago, for instance, we were talking about GS5 rumors with an on-board iris scanner for biometric authentication; now, another rumor says that iris scanning is a no-go, and Samsung will be doing fingerprint scanning, instead.

The fingerprint scanning business is one rumor that’s been hanging over Samsung going back to last spring, but that’s yet to translate into us seeing the feature on any new Samsung phones. This source suggests that Samsung is moving forward with such a scanner as opposed to iris-based tech because of the “unintuitive user experience of iris recognition.” The key bit there seems to be an issue with the range of the iris scanner Samsung was investigating, and the supposed need for users to hold the phone up to their face in order to authenticate.

As for the details behind the fingerprint scanner itself, Samsung may be able to integrate it into the phone’s display, which from a usability standpoint sounds nearly as good as Apple’s own front-mounted scanner.
